Nucleotide are composed of a photosphate group a sugar and nitrogenous base DNA Isela made up of long Strands of nucleotide which part of the above molécule can differ between nucleotides

The phosphate end and OH end of nucleotide in DNA differ from free nucleotides molecules.

Explanation:

5' phosphate group of one nucleotide and 3'-OH group of another nucleotide combine to form phosphodiester bond which holds the nucleotides in DNA molecule.

The phosphate end and OH end of nucleotide in DNA differ from free nucleotides molecules.

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms

above statement is not a true statement about the open ocean because the open ocean has low levels of nutrients. most of the photosynthetic activity on earth occurs in the open ocean within the photic zone. organisms in the deep ocean are exposed to frigid temperatures and total darkness but it does not begin at the low-tide mark.
